With this last patch when I run mask then build or, just build, when the process reaches the end of build. The TE closes but, the res file reflects the changes I'm testing offline.
When I place the tiny vbase "vbrmt" in the center of a painted village, the mask will remove all buildings and trees conflicting with the "vbrmt" object. I will remove that object and paint back the full village and other small house locations surrounding it. Then see if that constitutes an object conflict in a 1mile radius enough to cause the TE to close out at the end of the build. I had this problem in testing with a road that was too close to an airfield last year. Upon deleting all roads and tracks, the build stopped closing the TE at the end of it's run.
*NOTE*
The mask will remove houses from ground painted using the village tile if the ground is at a shallow slope. If I don't run the mask and only the build, the build is more slope tolerant for the houses in the village on shallow slopes. Since I'm in testing mode, the locations I want one or two village houses, I will level to see if the mask tolerates that and adjust the overall slope to account for the tiny step. First I will test removing the "vbrmt" from the village tile. I needed it for the 6 tank drones so I could gauge how well players can hide from a 500ft gallery 1.5 miles radius around them. At any give time I can only see maybe 3 of the 6 drones becasue of the village buildings and trees.
